Dispensing apparatus



March 10, 1942. D. B. MCDONALD DISPENSING APPARATUS Filed Dec. 19, 1940 Inventor a m W. M hm Attorney P ten ed Mar. 10, 1942 UNITED STATES PATENT 1 Claim.

This invention relates to new and useful improvements in liquid dispensers and more particularly to an apparatus for filling batteries.

The principal object of the present invention is to provide a filler for replenishing batteries with water and automatically cutting off the supply of water at the proper level.

Other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawing Figure 1 represents a side elevational View of the dispenser shown in filling relation with a battery, the latter being shown in fragmentary vertical section.

Figure 2 is a fragmentary vertical sectional view through the discharge end portion of the dispenser. 7

Referring to the drawing wherein like numerals designate like parts, it can be seen that numeral 5 generally refers to a conventional battery consisting of a case 6, plate I therein and a filler neck 8. In Figure 1 it can be observed that numeral 9 denotes the desired level of water over the plate 1.

In carrying out the present invention, a reservoir I is employed and has a neck II from which extends a rubber hose l2. At the discharge end of this hose is a control head generally referred to by numeral l3.

The control head l3 consists of an elongated tubular nozzle l4 having a laterally disposed chamber l5 into which a piston valve I6 is movable. This piston valve 16 has a stem H extending therefrom and through an opening in the nozzle I4 and on this stem and between the head 18 and the nozzle I4 is a compression spring IQ for normally maintaining the stem I! urged outwardly and the piston valve l6 closing or traversing the passageway through the nozzle l4. Obviously, when the stem I1 is pushed inwardly, the piston valve I6 is moved into the chamber l5 to free the passageway through the nozzle.

The nozzle [4 at one end is provided with a reduced neck or nipple 20 for insertion into the 4 corresponding end of the hose l2.

The remaining end of the nozzle 14 is bifurcated. In other words, this end last spoken of is formed with one or more slots 2| of a predetermined length and equivalent to the depths of water desired in the battery case '6, over the plate I.

It can now be seen, that when the reservoir I0 is inverted as shown in Figure 1 and the nozzle 14 disposed into the battery case 6 with the slotted end resting on the plate 1, opening of the passageway through the nozzle by disposing the piston valve l6 into the chamber [5 will permit water to enter the case 6. Water will continue as long as the valve i6 is in open position and until the level 9 reaches the upper ends of the slots 2|, whereupon air to the hose l2 will be cut off and no further amount of water will discharge from the nozzle. The attendant may then release the stem I1 and remove the nozzle from the battery. The water in the battery is now at the very proper level.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

In a battery filling device, a nozzle having a flat outer end for resting upon the upper edge of a battery plate, the nozzle being of elongated form to extend above the top of the battery when the nozzle is placed through the filling hole of the battery with the outer end of the nozzle resting on said plate, said end of the nozzle having an elongated longitudinally extending slot therein which passes through the outer end, said slot determining the height, along the nozzle, to

which the liquid may be admitted into the loattery, a laterally extending tubular boss on the upper part of the nozzle and located above the filling opening of the battery when the nozzle is resting on the battery plate, a valve member passing across the nozzle for closing the same and said valve member fitting in the boss when moved to open position, a shank on the valve member passing through a hole in the nozzle and having a head on its outer end and a spring encircling the shank and having one end bearing against the head and the other end against a part of the nozzle for holding the valve in closed position.
